[00:00:00] <XXCoder> ICH would know but he wont be on for some more hours
[00:01:14] <cncformywife> how i connect the granite x & y to the blocks?
[00:02:18] <XXCoder> bolts though holes in granite?
[00:02:59] <cncformywife> 3 intch granite...
[00:03:07] <cncformywife> inch*
[00:03:21] <XXCoder> yeah good question lol
[00:03:46] <cncformywife> jb-weld..
[02:30:55] <Deejay> moin
[02:48:20] <Loetmichel> cncformywife: oversized TC drill bit, 2k epoxy, threaded b-> done ;-)olts or dowels with metric inner thread
[02:48:28] <Loetmichel> ups
[02:48:50] <Loetmichel> cncformywife: oversized TC drill bit, 2k epoxy, threaded bolts or dowels with metric inner thread -> done ;-)
[02:50:25] <SpeedEvil> It's common to grease the thread, put on two nuts, and add epoxy.
[02:51:27] <SpeedEvil> you put the first nut on a bit proud of the surface, so torquing down the matching fitting doesn't load the granite
[02:53:18] <RyanS> Is this for using granite as a machine base?
[03:02:18] <Loetmichel> if i understoof cncformywife correctly: tor the granite beam that makes the gantry of a granite based machine ;-)
[03:02:29] <Loetmichel> to mount the SBr
[03:11:25] <cncformywife> Loetmichel: i'm here :)
[03:12:57] <cncformywife> what about countertop granite?
[03:14:49] <Loetmichel> you asked how to mount rails on a granite beam, didnt you?
[03:18:29] <RyanS> What would be cheaper to acquire a slab of granite or cast iron and, although I guess you need access to a vertical milling machine to machine cast-iron
[03:19:19] <SpeedEvil> Cast iron is more expensive than countertops
[03:19:38] * SpeedEvil wonders again about casting yourself.
[03:19:44] <SpeedEvil> (iron, not granite)
[03:20:34] <SpeedEvil> http://www.granitek.co.uk/ - interesting
[03:20:44] <SpeedEvil> 'As with ordinary concrete polymer concrete can be moulded into any shape or form in its pre-set state. When cured polymer concrete is much harder than conventional concrete and exhibits all of the material properties of hard granite.
[03:20:45] <RyanS> and countertops are flat enough?
[03:20:47] <Loetmichel> casting iron yourself is not without dangers
[03:21:46] <RyanS> you want to make a casting of yourself ? :P
[03:21:48] <SpeedEvil> Loetmichel: Well, no.
[03:21:54] <Loetmichel> especially when you intent to cast a machine base, with needs more than a few 100 grams of iron ;-)
[03:21:58] <SpeedEvil> RyanS: Who doesn't want a life-size statue of themself?
[03:22:12] <SpeedEvil> RyanS: On every streetcorner.
[03:22:21] <RyanS> Apparently there is a museum with bronze castings of genitals
[03:22:43] <cncformywife> how this thing work??
[03:22:44] <cncformywife> http://www.youtube.com/watch?v=Ppjz26BM1KQ
[03:23:46] <RyanS> Is the CNC actually for your wife or that a convenient way to justify the expense? :)
[03:24:49] <cncformywife> for my wife
[03:25:46] <cncformywife> she make jewelry and accessories
[03:26:06] <SpeedEvil> CNC jewlery seems kind-of-cheating
[03:26:34] <RyanS> Your wife sounds awesome, :) who doesn't want a wife and uses CNC
[03:26:53] <cncformywife> so i want small and precise cnc
[03:27:25] <cncformywife> now she work manualy and she has mor
[03:27:43] <cncformywife> more tools then me
[03:28:23] <cncformywife> but i'm open the jars :-)
[03:28:50] <RyanS> with a robotic arm
[03:29:24] <sivu_> i made my wife a ring from bronze with a lathe
[03:29:32] <SpeedEvil> I kinda want a nice 5 axis or more micromanipulator.
[03:29:46] <sivu_> she complained a bit when i bought the lathe but when i presented her a ring i made myself, the lathe was instantly justified
[03:29:59] <cncformywife> http://www.youtube.com/watch?v=wvpcsDQ-Jtw
[03:30:40] <cncformywife> RyanS: ^^
[03:30:49] <sivu_> also building a cnc mill was ok when i said we need one to engrave the welcome plate to the door
[03:31:34] <cncformywife> the cnc was her idea
[03:32:09] <cncformywife> she start with solidworks..
[03:32:12] <RyanS> I think I better purchase a CNC before I get into any sort of relationship " Sorry, it's too late"
[03:32:30] <cncformywife> i'm only the builder
[03:34:02] <cncformywife> "Sorry, it's two lathes"
[03:34:09] <RyanS> if I was a woman, I would want to be married to you
[03:34:45] <sivu_> now that i have a cnc router, i will start building a new one
[03:34:50] <cncformywife> it's fine i'm bisexual :)
[03:35:08] <RyanS> Okay, let's get married
[03:35:37] <RyanS> And you can build me CNC
[03:36:10] <RyanS> I am in Australia, we are to backward to allow
[03:36:45] <cncformywife> ok i will ask my wife about that :)
[03:37:04] <RyanS> Sure no hurry :P
[03:37:35] <cncformywife> she say NO!!!
[03:37:45] <gonzo_> or run away with his wife, you could win half a cnc machine in the settlement
[03:38:10] <RyanS> That's okay, just thought I would ask
[03:38:36] <cncformywife> you need 4 axis to do it equal :(
[03:39:13] <RyanS> No no no, five axis minimum
[03:39:30] <cncformywife> 5 it's not the max?
[03:39:35] <SpeedEvil> RyanS: that's $100 or so
[03:39:47] <SpeedEvil> https://www.youtube.com/watch?v=N1HNnDdHygo - $20 axes.
[03:39:51] <cncformywife> 100$??
[03:40:54] <cncformywife> SpeedEvil: yes, it's multi direction milling.
[03:41:29] <RyanS> Axe murderer
[03:46:25] <RyanS> 5C or ER32, of for work holding? I don't want to have to stock two types, if possible. ER 32 would be economical solution
[03:47:18] <cncformywife> what spindle you have?
[03:49:21] <RyanS> I was more referring to. If I get a milling machine, I'm thinking of 4 axis. And you can go ER32 or 5C
[03:52:07] <cncformywife> i think 5c have drowbar
[03:52:15] <cncformywife> and ER32 not,
[03:53:02] <cncformywife> if you have drowbar you can make power drowbar and have ATC.
[03:55:43] <cncformywife> RyanS: ^
[03:55:54] <cncformywife> what machine do you want?
[04:01:50] <cncformywife> the SBR12UU have backlash?
[04:02:01] <RyanS> tormach 770, I don't have time or skills to build or convert
[04:04:34] <RyanS> I could be totally mistaken, but 4 axis would perhaps save the setup time?
[04:04:59] <cncformywife> i'm almost buy the 1100
[04:05:12] <cncformywife> but i see it is stepper.
[04:06:03] <Loetmichel> cncformywife: how can a linear way have bnacklash?
[04:06:10] <RyanS> Two large for me. But apparently if you don't machine large parts, which are usually don't. 10,000 RPM is going to machine some things quicker
[04:06:18] <SpeedEvil> Loetmichel: Some machine makers are very skilled
[04:06:18] <Loetmichel> that is something a ballscrew has or hasnt
[04:06:52] <Loetmichel> a linear way can tilt or rattle... but backlash?
[04:07:25] <Loetmichel> that is reserved for the leadscrews ;-9
[04:07:30] <SpeedEvil> 'Butterways, we supply everything with backlash! Including bolts!'
[04:08:42] <cncformywife> move to the side.. be wobble
[04:08:50] <RyanS> How to multitasking lathes index the spindle. As far as I understand they use direct drive induction motor? I guess they have a stepper motor and automated gearbox? couple to the spindle
[04:09:17] <SpeedEvil> you can in principle use an induction motor at zero speed to provide torque
[04:09:56] <SpeedEvil> you'd need some form of feedback of course, and a stepper might be easier
[04:09:57] <cncformywife> so the SBR12UU have backlash? ?
[04:10:50] <RyanS> Because the videos I see they run up to full speed all the way down to like five rpm, and presumably don't backdrive
[04:11:02] <cncformywife> for mor than 15$ i want servo, thay give you rotory table for 4.5K$ and for 8K$ stepper CNC
[04:11:40] <cncformywife> rotory table is max 500$ + motor + conroler = 1000$ maX
[04:11:43] <RyanS> actually well servo motor is simply an induction motor connected to a gearbox and a controller?
[04:12:13] <RyanS> I'm thinking like those multitasking milling/turning centres
[04:12:45] <cncformywife> this is how i think too.
[04:13:04] <RyanS> And 300 hours of man hours to build it.....
[04:13:25] <cncformywife> from granite!
[04:13:27] <RyanS> Personhours
[04:13:38] <SpeedEvil> beinghours
[04:13:56] <SpeedEvil> On the internet, nobody knows you're a walrus trying to build a CNC
[04:14:17] <cncformywife> 300*20$=6000$
[04:15:01] <cncformywife> 300/40= 7.5 monts
[04:15:46] <RyanS> I don't know how long it takes I was just assuming
[04:15:51] <cncformywife> but i dont have a job :( :( :(
[04:16:21] <cncformywife> how long take waht?
[04:16:24] <RyanS> I just guess you have to be into doing it
[04:16:31] <RyanS> To build a CNC
[04:17:41] <RyanS> I do want to build lathe, it seems to be more straightforward to me
[04:17:43] <cncformywife> i want something good for the price. the 1100 is very good but not for the price.
[04:18:31] <cncformywife> the forces on lathe is extremely high
[04:18:44] <cncformywife> if you want to machine metal.
[04:18:45] <RyanS> Unfortunately, I think it's the cheapest option if you want something that works, :(
[04:19:09] <RyanS> I'm not sure about that, . I thought they are more efficient than milling
[04:19:45] <cncformywife> i have bad experiance with the HF lathe.
[04:19:57] <cncformywife> it was 450$
[04:20:05] <cncformywife> but pure crap
[04:20:18] <RyanS> I think that would be the really small
[04:21:01] <cncformywife> i try to machine wood - work. metal - stuff start move.. bad bad finish.
[04:21:28] <RyanS> We have 150 mm 550 mm, 750w. It's actually not too bad, we can cut about 2 mm in stainless steel
[04:21:32] <cncformywife> i retaen it after few days
[04:21:46] <RyanS> sorry 350
[04:22:07] <RyanS> and 550 w
[04:22:10] <cncformywife> 2mm steel? in dia?
[04:22:29] <RyanS> depth of cut
[04:22:35] <cncformywife> hoooo
[04:22:40] <cncformywife> i see,,
[04:22:58] <cncformywife> in the HF 0.1 and you kill the machine...
[04:23:31] <RyanS> And can do 3 mm in mild steel acceptably, but three is a bit too much for stainless, it will tolerate it. Okay, but not brilliant
[04:23:36] <cncformywife> maybe for brass is good.. i havent try..
[04:24:01] <RyanS> Strangely, we don't seem to and get a lot more than three out of aluminium
[04:27:02] <RyanS> I can't believe how much brass chips spray all over the place
[05:12:04] * Loetmichel is just milling a new computer connector backplate out of 3mm aluminium... tha speaker grill took a while... http://youtu.be/BWTTP0RomA0
[05:15:20] <Loetmichel> *aaand done: http://www.cyrom.org/palbum/main.php?g2_itemId=15002
[05:30:29] <TekniQue> Loetmichel: neat
[06:54:17] <jthornton> I get a lot of burs on the far side when drilling thin materials... I wonder if my feed is too fast
[07:29:30] <SpeedEvil> Backer board is an answer
[07:53:40] <jthornton> the thin material just lifts up...
[08:04:14] <SpeedEvil> Clamp it down.
[08:04:20] <SpeedEvil> Or use vacuum
[08:04:25] <SpeedEvil> Or a top board
[09:24:57] <JesusAlos> hi
[09:40:44] <Loetmichel> sooo, it starts to take form... a few things to fix with screw, a few cables to build/sort out, a frontflap with lock, a lid-> done ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=15005
[09:44:45] <jdh> how do you test these?
[09:52:33] <Loetmichel> jdh: in a measurement chamber
[09:53:59] <jdh> bah... the other half of my 6040 is 100 mile away but I can't get it until monday
[09:54:30] <XXCoder> heys
[10:54:03] <CaptHindsight> if you need the granite base to insure sub-micron accuracy while engraving, then I'd suggest the Rockwell air bearing linear servo positioners to go with it
[10:55:19] <CaptHindsight> sounds like very precision engraving for jewelry
[10:55:32] <XXCoder> maybe
[10:55:41] <JesusAlos> by
[11:00:34] <CaptHindsight> sounds like shenanigans, I wonder what he's really up to
[11:01:24] <XXCoder> dunno but did you see the crappy lathe video I linked?
[11:01:42] <CaptHindsight> was the lathe or the video crappy?
[11:02:47] <XXCoder> kinda both lol but surpising effective lathe for drill and screws type
[11:55:35] <IchGuckLive> hi all B)
[11:56:06] <IchGuckLive> happy 4th juli to the USA hope nowone is under the bad weather influence
[11:56:21] <IchGuckLive> Hurricane Dust storm
[11:56:36] <IchGuckLive> what a miss on holiday
[11:56:48] <jdh> lots of rain here but the storm was gone by midnight
[11:57:39] <IchGuckLive> here its building up after a near Sahara like DAY no thunder till now
[11:57:52] <IchGuckLive> but realy dark clouds and some rain
[11:58:55] <XXCoder> hey ich
[11:59:00] <IchGuckLive> RyanS: you shoudt have told cncformywife that a moldmaker for cakes can earn alot of money
[11:59:07] <XXCoder> you ever played with epoxy grtinite?
[11:59:29] <IchGuckLive> only to cote Foam
[12:00:38] <SpeedEvil> XXCoder: I linked that before
[12:00:54] <XXCoder> the el cheapo wood lathe?
[12:00:56] <SpeedEvil> http://www.granitek.co.uk/highAccuracy.html
[12:01:03] <XXCoder> oh that.
[12:02:28] <IchGuckLive> XXCoder: what is the goal to be met by your mold stuff
[12:02:38] <IchGuckLive> Garden figur
[12:02:48] <IchGuckLive> Stone imitates
[12:02:51] <XXCoder> none, was just checking into it for fun
[12:02:59] <IchGuckLive> ah
[12:03:13] <XXCoder> other was considering it for his wife's jewelery cnc
[12:03:48] <syyl_ws_> our new vmc has epoxy granite parts...
[12:04:14] <IchGuckLive> there are so many concrete mills out now
[12:04:29] <IchGuckLive> with fiber incredians
[12:04:39] <IchGuckLive> they dont shake at all
[12:04:58] <IchGuckLive> See HERMLE C type
[12:05:03] <syyl_ws_> in the imagination of the engineer
[12:05:11] <syyl_ws_> the machinist will shake the crap out of it.
[12:05:21] <IchGuckLive> oh now its real at full load
[12:05:24] <ssi> never shake a baby
[12:05:27] <ssi> or a mill
[12:06:38] <syyl_ws_> ever helical interpolatet a small hole with to much feed? ;)
[12:09:58] <IchGuckLive> lots of rain moving towards loedmiches position http://www.wetter.com/wetter_aktuell/niederschlagsradar/deutschland/
[12:10:28] <syyl_ws_> this just got #linuxweather
[12:10:55] <DaViruz> lets build an open source weather control sustem
[12:11:19] <IchGuckLive> DaViruz: lots of out
[12:11:24] <IchGuckLive> worldwide
[12:11:25] <ssi> beautiful here... scattered 5000' or so, visibility unlimited
[12:11:30] <ssi> cause america ;)
[12:12:03] <DaViruz> we've jad unlimited rain the past two weeks
[12:12:15] <DaViruz> probably because i'm on vacation
[12:12:16] <IchGuckLive> the sun shines at any time somwhere on the globe
[12:12:38] <IchGuckLive> vacation is bad on weathere
[12:12:51] <IchGuckLive> you always pick the wrong point or date
[12:14:00] <DaViruz> i didn't get what i picked. pretty sure the weather will be awesome on the days i picked
[12:14:43] <IchGuckLive> oh the firerwork is canceld true to thunderstorm activety but the C17 and C5 comming in here as usuael
[12:16:27] <ssi> gonna get a ride? :P
[12:16:38] <IchGuckLive> on a cycle O.O
[12:33:37] <cncformywife> hi
[12:34:04] <cncformywife> where i can find 1"X2" brass?
[12:34:42] <ssi> I buy stuff like that from mcmaster-carr
[12:36:08] <IchGuckLive> hi cncformywife
[12:36:31] <IchGuckLive> where are you in our still blue world im in germany
[12:37:16] <IchGuckLive> you shoiudt make cake moldes female love this stuff and or choclate bar Aluminium fun stuff
[12:40:08] <ssi> https://www.youtube.com/watch?v=HN1xSIgnwDA
[12:40:20] <cncformywife> in usa
[12:41:30] <cncformywife> ssi: you need cnc for making this rail for the cnc
[12:42:28] <ssi> nah, that could be made by hand
[12:43:21] <IchGuckLive> cncformywife: is you budget as low as 450USD
[12:43:41] <cncformywife> ~
[12:43:56] <cncformywife> where i can find 1"X2" brass? in the usa??
[12:44:03] <IchGuckLive> reading the lgs as loged tonight
[12:44:26] <IchGuckLive> cncformywife: your local stel shop
[12:44:33] <IchGuckLive> steel
[12:44:44] <IchGuckLive> he also knows where to by NE
[12:44:49] <archivist> steel shops do not sell brass!
[12:45:10] <jdh> cncformywife: http://www.onlinemetals.com/merchant.cfm?pid=1517&step=4&showunits=inches&id=1296&top_cat=79
[12:45:46] <IchGuckLive> Homedepo got also nice brass sorts in stock
[12:45:58] <jdh> not that big
[12:46:01] <cncformywife> i want to make nut.
[12:46:03] <IchGuckLive> agree
[12:46:24] <jdh> I'd look on ebay for that small
[12:46:41] <archivist> you buy hex drawn bar for nuts
[12:46:41] <cncformywife> 70$
[12:46:43] <cncformywife> WOW
[12:46:55] <cncformywife> HALF of my CNC
[12:46:58] <cncformywife> OMG
[12:47:03] <IchGuckLive> cooper is expensive this time so brass will aso be
[12:47:20] <cncformywife> what about bonze ?
[12:47:39] <IchGuckLive> even more
[12:47:48] <IchGuckLive> what is it for
[12:48:00] <cncformywife> nut
[12:48:19] <IchGuckLive> why not use a ACME cheep one
[12:48:29] <IchGuckLive> or ready made
[12:48:37] <cncformywife> what is ACME??
[12:48:42] <IchGuckLive> the TR are real cheep
[12:49:40] <cncformywife> what about plastic?
[12:49:42] <IchGuckLive> AcetylCarbonMeateEther
[12:49:49] <IchGuckLive> ACME is it
[12:50:06] <IchGuckLive> PA also got cheep in TR stuff
[12:50:15] <IchGuckLive> i got them in y Foam masgines
[12:50:23] <IchGuckLive> PA6.6
[12:50:55] <cncformywife> PTFE is good?
[12:51:19] * jthornton goes to see the Nitty Gritty Dirt band... I assume they are as old a dirt now
[12:51:48] <IchGuckLive> PolyTetraFlurEtylen ZEFLON
[12:51:51] <IchGuckLive> T
[12:52:10] <IchGuckLive> Teflon is the user nale here in Europ
[12:52:36] <Jymmm> jthornton: Walkers and wheelchairs!
[12:53:13] <jdh> for the audience or the band?
[12:53:41] <Jymmm> jdh: Yes
[12:54:14] <IchGuckLive> cncformywife: what thread you got on your axis spindles
[12:55:20] <IchGuckLive> as you try to stay cheep go to the local hardware store and ask for Kitchen Catalog they got plenty of stuff for CNC makers
[12:55:49] <IchGuckLive> also Driven spindles for moving TV platforms
[12:56:05] <Jymmm> Oh, their really not THAT old, just sounding more country than folksong
[12:56:06] <IchGuckLive> so as Eelctronic Storiges for Tins
[12:56:33] <Jymmm> https://www.youtube.com/watch?v=5B7HsJo-bcc&feature=kp
[12:56:40] <IchGuckLive> at 10USD you got stuff at 3feet long
[12:57:09] <IchGuckLive> spindle nut and holders
[12:57:21] <kfoltman> cncformywife? what kind of nick is THAT :O
[12:57:37] <kfoltman> (probably better than 'mycncwife' though)
[12:57:48] <IchGuckLive> kfoltman: the last standof !
[12:58:06] <kfoltman> IchGuckLive: brass M3 hexagonal one?
[12:58:48] <IchGuckLive> O.O in the kitchen that tiny no way
[12:59:19] <SpeedEvil> IchGuckLive: Who needs ways, when you have full extension drawer slides?
[12:59:36] <kfoltman> IchGuckLive: I'm talking about this https://www.google.com/search?q=brass+standoff&client=iceweasel-a&rls=org.mozilla:en-US:unofficial&tbm=isch
[12:59:37] <IchGuckLive> You got it
[13:00:11] <kfoltman> SpeedEvil: you can have my crappy linear rails when you pry them out of my cold, dead CNC machine
[13:00:25] <IchGuckLive> by the Way the new 14.10 HeekscadCNC version is out
[13:01:23] <ssi> adafruit sells 15mm profile rail relatively cheap now
[13:01:24] <ssi> https://www.adafruit.com/products/1861
[13:01:29] <cncformywife> wood nut wiil work?
[13:01:43] <cncformywife> i want to use this threded rod
[13:01:50] <kfoltman> ssi: it's probably not the rail that's a problem, it's carriages
[13:01:53] <IchGuckLive> id build tomorrow a new version CNC with the cheep CH V-Shape bearings i owned 20pc at 15USD lets see how it comes out on just Sqare precise steel
[13:01:59] <ssi> they have carriages too
[13:02:16] <cncformywife> http://www.lowes.com/pd_44610-37672-11028.0_0__?productId=3128773&Ntt=threaded+rod&pl=1&currentURL=%3FNtt%3Dthreaded%2Brod&facetInfo=
[13:02:16] <ssi> I dunno what the quality's like
[13:02:22] <ssi> but for the price it might be worth finding out
[13:03:53] <cncformywife> it will work for lead screw?
[13:04:08] <IchGuckLive> no way
[13:04:14] <SpeedEvil> cncformywife: yes.
[13:04:18] <SpeedEvil> With extreme caveats.
[13:04:21] <kfoltman> cncformywife: it will work for the first 5 seconds ;)
[13:04:26] <SpeedEvil> To the point that in many cases, it may be no
[13:04:27] <kfoltman> and not very well
[13:04:44] <IchGuckLive> not even close to a look for CNC stuff
[13:04:49] <SpeedEvil> I have wondered how long rolled SS allthread would last - if kept sell lubricated
[13:04:54] <SpeedEvil> well
[13:04:54] <IchGuckLive> dont they got Trapezional
[13:05:18] <kfoltman> SpeedEvil: I have some zinc-plated allthreads, they're truly awful
[13:05:22] <IchGuckLive> im off BYE
[13:05:26] <SpeedEvil> kfoltman: yeah - zinc plated is failure
[13:05:27] <kfoltman> SpeedEvil: that's all I can get in Ireland
[13:05:42] <XXCoder> order online?
[13:05:57] <Loetmichel> get a fitting thread gutter adn cut the zinc off
[13:06:01] <Loetmichel> cutter
[13:07:11] <SpeedEvil> Loetmichel: sulphutic acid
[13:07:26] <Loetmichel> will eat the steel
[13:07:49] <ssi> http://www.mcmaster.com/#99030a105/=soy8xg
[13:07:53] <SpeedEvil> not fast
[13:08:37] <SpeedEvil> http://www.orbitalfasteners.co.uk/en/products/m10x1m-stainless-steel-studding-threaded-rod-a2-304-din-975-
[13:10:03] <syyl_ws_> citric acid will remove the zink
[13:10:11] <syyl_ws_> and stainless will gall
[13:10:29] <cncformywife> http://www.lowes.com/pd_142075-37672-881653_0__?productId=3013471&Ntt=coupling+nut+13&Ns=p_product_price|0&pl=1&currentURL=%3FNs%3Dp_product_price%7C0%26Ntt%3Dcoupling%2Bnut%2B13%26page%3D1&facetInfo=
[13:10:30] <SpeedEvil> If you use stainless nuts
[13:11:00] <Jymmm> THIS IS AWESOME... http://www.liveleak.com/view?i=96b_1372272476&comments=1
[13:11:02] <syyl_ws_> right
[13:11:13] <cncformywife> stainless nuts is good?
[13:11:15] <Jymmm> Read the comments too, funny!
[13:11:23] <syyl_ws_> no
[13:11:32] <syyl_ws_> worst combination, cncformywife
[13:12:27] <cncformywife> so what to use?
[13:12:40] <syyl_ws_> brass, bronce or plastic
[13:12:41] <cncformywife> plain steel?
[13:15:19] <cncformywife> cant find
[13:16:16] <cncformywife> what is the problem with regular steel?
[13:18:14] <cncformywife> what about tapping fake wood?
[13:18:48] <SpeedEvil> The problem is that the thread is not designed for use as leadscrews.
[13:19:54] <cncformywife> where i can find leadscrews?
[13:20:01] <SpeedEvil> Depending on what sort of allthread, one or more of: Nonlinear screw pitch, roughness leading to wear, bent screw, wrong material may cause problems
[13:20:23] <SpeedEvil> http://www.ebay.co.uk/itm/TR12x3Dx1000mm-Trapezoidal-Acme-Ballscrew-Leadscrew-/310192798942?pt=UK_BOI_Metalworking_Milling_Welding_Metalworking_Supplies_ET&hash=item4838ee7cde
[13:21:00] <SpeedEvil> https://en.wikipedia.org/wiki/Trapezoidal_thread_forms
[13:21:52] <cncformywife> how it connect to the motor??
[13:22:05] <SpeedEvil> Generally, blutak
[13:22:48] <cncformywife> what is blutak?
[13:23:11] <cncformywife> http://en.wikipedia.org/wiki/Blu-Tack
[13:23:23] <cncformywife> it is like epoxy?
[13:26:08] <Jymmm> poster putty
[13:27:33] <Jymmm> Here's a project for you woodworkers... https://www.youtube.com/watch?v=xg1J3tdfUFY
[13:27:45] <kfoltman> SpeedEvil: heh, I don't know how much torque can blue tack transfer, but... not enough :D
[13:28:04] <kfoltman> SpeedEvil: how about chewing gum?
[13:28:09] <kfoltman> would chewing gum work?
[13:28:22] <Jymmm> kfoltman: gum dries out, post putty doesn't =)
[13:28:27] <Jymmm> poster*
[13:28:58] <Jymmm> kfoltman: 5, 10 years later and you can still use the stuff =)
[13:29:05] <SpeedEvil> More seriously, a coupler of some form.
[13:29:15] <SpeedEvil> http://www.ebay.co.uk/itm/TR10x4-P2D-Multi-Start-Trapezoidal-Leadscrew-Spindle-500mm-Nut-KSM10x4-P2-/221330475067?pt=UK_BOI_Metalworking_Milling_Welding_Metalworking_Supplies_ET&hash=item338853083b
[13:29:47] <kfoltman> SpeedEvil: and how do you attach that nut to everything else?
[13:30:07] <kfoltman> mill a mating cavity?
[13:30:10] <SpeedEvil> Well, that's a fairly low-stress joint, so post-it-notes.
[13:30:36] <kfoltman> I don't know what's so low-stress about it
[13:31:48] <kfoltman> also, multistart is asking for trouble I think
[13:32:58] <kfoltman> SpeedEvil: definitely not hobbyist friendly, that nut
[13:33:21] <kfoltman> excluding hobbyists with lathes
[13:36:15] <kfoltman> cncformywife: http://www.ebay.ie/itm/261072451805 that's what I used, more or less
[13:37:30] <kfoltman> cncformywife: plus 3 of this: http://www.ebay.ie/itm/151215720718
[13:38:33] <kfoltman> (well, to be *totally* honest, I only have 2 of these, the third one was a full Z linear stage bought second hand from some South Korean ebayer)
[13:39:00] <kfoltman> you still need some sort of precision rails for this though
[13:39:13] <Jymmm> kfoltman: (You lyng bastard you =)
[13:39:39] <LeelooMinai> You can also buy whole sets with rails for good price there - that's what I did for my cnc - just bought rails + ballscrews + blocks
[13:40:05] <kfoltman> LeelooMinai: that, too
[13:40:09] <kfoltman> by the way
[13:40:13] <kfoltman> speaking about rails
[13:40:41] <kfoltman> it makes sense to order some extra carriages (blocks) for those rails, the ones they usually provide are nasty
[13:40:50] <maZer`-> hi all :)
[13:41:06] <Jymmm> kfoltman: nasty?
[13:41:15] <kfoltman> Jymmm: badly made
[13:41:23] <Jymmm> kfoltman: ah
[13:41:35] <kfoltman> they take the LM12UU linear bearings and just cut them open with angle grinder or something
[13:41:45] <kfoltman> without too much regard for the angle of the cut
[13:41:55] <LeelooMinai> The blocks that attach to nuts I bought separatelly - since I have rails that are 2cm and ballscrew that is 16 - I needed ones that will make for the difference
[13:41:56] <kfoltman> and, for example, whether or not the cut is too close to the ball races
[13:42:26] <kfoltman> LeelooMinai: ah, I didn't and had to do some nasty hacks to make up for it
[13:44:32] <kfoltman> cncformywife: but, all in all, the ballscrew+rail set-up is relatively easiest to put together, especially if you don't have access to advanced tools
[13:45:37] <kfoltman> LeelooMinai: do you mill PCBs?
[13:46:07] <LeelooMinai> kfoltman: I am changing floors in my house for mom:/
[13:46:19] <LeelooMinai> kfoltman: Instead of playing with almost-finished CNC
[13:46:26] <LeelooMinai> Sad
[13:46:29] <kfoltman> LeelooMinai: ah!
[13:46:37] <kfoltman> well, mildly annoying I suppose
[13:46:55] <kfoltman> yay have a new toy, boo can't play with it
[13:47:50] <LeelooMinai> Also, I need to wait for some money - I want to buy that mesa set and maybe surface plate to test the CNC for accuraccy - tons of things I want to do yet. Then I need to make some kind of acrylic or polycarbonate cover for it, etc
[13:48:18] <LeelooMinai> It's a bit of money sink toy:)
[13:48:51] <LeelooMinai> And I am not even at the stage of getting the spindle + all bits for milling and some clamping solution
[13:53:08] <kfoltman> LeelooMinai: it's an expensive hobby
[13:58:24] <Jymmm> All hobbies are expensive
[13:59:43] <SpeedEvil> Writing.
[14:00:29] <kfoltman> SpeedEvil: trolling
[14:00:37] <Loetmichel> LeelooMinai: cannt say that it is a money sink
[14:00:41] <LeelooMinai> Well, most hobbies usually get expensive if one really gets deep into them - begins to buy specialized tools, more accurate, more reliable, tries doing exotic projects, etc.
[14:00:45] <Loetmichel> the oposite
[14:01:10] <Loetmichel> it has saved me lots of money for model pats in the last 2 decades ;-)
[14:01:16] <Loetmichel> parts
[14:01:18] <LeelooMinai> Loetmichel: I mean for a hobbyist. I guess if you actually say what you make, it will pay back.
[14:01:31] <LeelooMinai> say=sell
[14:01:39] <Loetmichel> i didnt sell any
[14:01:58] <Loetmichel> but i saved so much money in making my own parts.
[14:02:09] <LeelooMinai> Well, yes, I guess once you have it going you can make parts that one would otherwise have to buy, but I am not at this stage.
[14:02:15] <kfoltman> You can't really make any serious device without having access to a CNC router or at least a laser cutter
[14:02:25] <SpeedEvil> Well, if the money saved was parts that go toward the hobby...
[14:02:33] <Loetmichel> for example: one copter chassis similar to this will cost about 200 eur: http://www.cyrom.org/palbum/main.php?g2_itemId=12997
[14:02:45] <LeelooMinai> First you need to reach the stage when everything is working - and it's a long way to get there for someone without a lot of money.
[14:02:49] <Loetmichel> ... it had cost me less than 15 eur in aluminium and a bit of paint
[14:03:07] <Loetmichel> SpeedEvil: OTHER hobby
[14:03:16] <Loetmichel> so the machine isnt the money sink ;-)
[14:03:25] <Loetmichel> the other hobbys are
[14:03:25] <SpeedEvil> ah
[14:03:28] <jdh> so I went to Lowes to buy some MDF for my router. Then I remembered I don't use MDF, it's just particleboard
[14:03:31] <Loetmichel> .. and the wife of course
[14:03:54] <SpeedEvil> MDF is good in some ways
[14:04:15] <LeelooMinai> Particle board is kind of terrible in almost any respect
[14:04:33] <kfoltman> is there a difference between particle board and hdf?
[14:04:47] <jdh> but, particle board is better than MDF (for this)
[14:05:09] <SpeedEvil> For what?
[14:05:25] <jdh> spoilboard
[14:05:34] <SpeedEvil> Well, I guess.
[14:07:08] * kfoltman is trying to install machinekit on an old microsd card
[14:19:18] <Loetmichel> i would unse marine plywood or (better) a foam plasic like sikablock for spoilboard
[14:19:31] <Loetmichel> because you can use water on it to cool the mill bit
[14:34:22] <maZer`-> hi all :)
[14:35:36] <kfoltman> so, there's at least some progress: I got machinekit to run on my BBB
[14:35:43] <kfoltman> but the GUI is unbelievably slow
[14:35:52] <kfoltman> is that just a fact of life, or am I doing something wrong?
[14:36:05] <cradek> both, when using a BBB
[14:36:09] <Jymmm> That's BBB as I understand it.
[14:36:18] <Jymmm> Hey cradek!
[14:36:20] <cradek> seems they're shockingly slow
[14:36:21] <kfoltman> running Axis(?) over ssh -X
[14:37:08] <kfoltman> is there a text-based interface, or a remote protocol that only sends commands?
[14:37:23] <Jymmm> keystick
[14:37:30] <cradek> there are both, but they both suck
[14:38:08] <kfoltman> back to grbl then?
[14:38:14] <Jymmm> cradek: keystick is eh, but what was the pre-axis one?
[14:38:25] <cradek> don't you have a real computer you can use?
[14:38:34] <cradek> they're free on every street corner
[14:38:37] <kfoltman> cradek: not really, no
[15:14:48] <Loetmichel> i gifted my co-worker a laptop today... because his wife has lurched away his old one with "i NEED this!" a few weeks ago. His look in complete disbelief... he couldnt believe it. i even installed his beloved dynablaster in a dosbox... he was happy as fuck ;-) ( and i would like to see his wifes face when she sees what happens when she snatches an old netbook from him ;-) -> this is the one
[15:14:49] <Loetmichel> i gifted him today: http://www.ebay.de/itm/321448436239 ... and it really looks like new ;-)
[15:17:02] <skunkworks_> very nice!
[15:19:01] <SpeedEvil> Loetmichel: :)
[15:19:10] <Loetmichel> i REALLY want to see his wifes face when she sees it and compares it to the snatched netbook, though ;-)
[15:19:30] <maZer`-> im trying to tune my pid
[15:20:03] <Jymmm> jthornton: JT-Shop Since you have bandwidth again, This is a bit long, but kinda neat… https://www.youtube.com/watch?v=N2utaZzmBWA
[15:20:09] <maZer`-> but i got a problem, if i travel in one direction i have about 50m f-error on beginng of the ride and on the end
[15:20:21] <maZer`-> can someone help me to solve it :(
[15:20:44] <maZer`-> is my p value to high (got 100)
[15:26:05] <pcw_home> maZer%60- what type of servo? (velocity or torque mode)
[15:30:41] <kfoltman> Loetmichel: can it run linuxcnc? ;-)
[15:33:27] <Loetmichel> it could, no lpt port though
[15:33:49] <skunkworks_> like my test bench? http://electronicsam.com/images/KandT/testing/DSC_1814.JPG
[15:36:17] <maZer`-> ahm thats a good question
[15:36:19] <maZer`-> also 0-10v
[15:36:21] <maZer`-> dc servo
[15:36:28] <maZer`-> should be velocity ? :)
[15:37:02] <pcw_home> do the drives have tachometers?
[15:37:15] <maZer`-> yes but tachometers are connected to servo controllers
[15:37:32] <pcw_home> OK so very likely velocity mode
[15:37:40] <maZer`-> yes :)
[15:38:02] <pcw_home> so for velocity mode tuning, FF1 does the heavy lifting
[15:38:59] <maZer`-> yes i tuned ff1
[15:39:07] <maZer`-> so that the f-error is minimum
[15:39:20] <maZer`-> but i have only problems on the end of a travel or the beginning
[15:39:21] <maZer`-> :(
[15:39:35] <pcw_home> did you tune FF2?
[15:39:59] <maZer`-> yes i did
[15:40:12] <maZer`-> im not sure my machine got backlash or not
[15:40:32] <maZer`-> but backlash should not be visible on end of a travel :(
[15:40:34] <pcw_home> encoder on motors or linear scales?
[15:40:39] <maZer`-> linear encoders
[15:40:49] <maZer`-> haidenhain 0.005
[15:41:03] <pcw_home> ahh backlash may well be an issue then
[15:41:14] <Jymmm> How do you cut 100 rods to (various) lengths easily?
[15:41:53] <maZer`-> pcw_home can i measure backlash with f-error
[15:42:33] <Loetmichel> Jymmm: cutting saw wiht adjustable endstop?
[15:42:57] <Jymmm> Loetmichel: Sounds too "manual"
[15:43:02] <pcw_home> pretty hard to tell unless you physically turn the motor shaft while watcing the DRO
[15:43:37] <Loetmichel> Jymmm: put a stepper motorm a leadscrew and a small µc on the endstop
[15:43:38] <Loetmichel> ;-)
[15:43:43] <maZer`-> i mean
[15:43:47] <Jymmm> lol
[15:43:49] <maZer`-> f-error is the value in mm
[15:43:50] <Jymmm> Loetmichel++
[15:44:00] <maZer`-> if i got 50m f-error it means i got 0.05mm backlash?
[15:47:56] <skunkworks_> maZer`-: no... you have to physically measure it...
[15:53:32] <maZer`-> skunkworks_ ok :(
[16:03:15] <Aero-Tec> having some trouble
[16:04:07] <Aero-Tec> using version 8.04
[16:04:24] <Aero-Tec> not able to get updates
[16:04:48] <cradek> do you mean ubuntu updates or linuxcnc updates?
[16:04:50] <Aero-Tec> this computer has been sitting a long time
[16:05:01] <Aero-Tec> my other ones update fine
[16:05:11] <Aero-Tec> ub
[16:05:18] <Aero-Tec> the system
[16:05:44] <Aero-Tec> seem like 8.04 is not supported any more
[16:05:46] <cradek> I am surprised they are still available. sounds like you should compare your sources.list entries
[16:06:05] <Aero-Tec> have to look and see what the other ones are running
[16:06:31] <Aero-Tec> could be 10.04
[16:06:47] <Aero-Tec> will do
[16:06:48] <cradek> ubuntu 8 was end-of-lifed in May 2013
[16:06:49] <Aero-Tec> thanks
[16:07:18] <cradek> er no, May 2011
[16:07:24] <cradek> anyway, in the past
[16:08:06] <cradek> ubuntu 10 will have some updates until April 2015
[16:12:10] <Jymmm> EOL doens't mean it's not useful
[16:12:37] <Jymmm> Even roadkill can be useful as fertilizer
[16:13:27] <cradek> that is orthogonal to the question of why updates are not available
[16:30:57] <gkamysz> I updated a machine from 2.2.8 to the latest the the other day. it was easier just to use a new live disk.
[16:32:26] <Jymmm> heh
[16:32:56] <gkamysz> i was worried the old box wouldn't handle 10.04 but I think it runs better, at least I have 1280x1024 now.
[16:34:29] <gkamysz> i downloaded the update to 10.04, and after 2+ hours of installing I killed and the disk installed in 15 minutes.
[16:40:05] <Jymmm> Interesting... RECHARGABLE coin cell Li-Ion battery... http://www.adafruit.com/products/1572
[16:45:00] <Aero-Tec> the mill is 10.04, the lathe 8.04
[17:11:26] <Aero-Tec> doing the web update
[17:11:51] <Jymmm> update or upgrade?
[17:12:30] <Aero-Tec> upgrade, sorry
[17:12:43] <Jymmm> no comment
[17:19:04] <ve7it> Jymmm, hey
[17:20:03] <Jymmm> ve7it: howdy!
[17:20:25] <ve7it> I have used those batteryies in some projects... they work well
[17:20:46] <Jymmm> ve7it: Nice, did you see the USB charger for them too?
[17:21:10] <Jymmm> (same page)
[17:22:22] <ve7it> I built a little charger using a microchip mcp73832 for it (built into project so all that it needs is 5V from anything to charge it.
[17:22:34] <Jymmm> ah gotcha
[17:23:05] <ve7it> 17ma charge rate... takes about 3 hours
[17:23:15] <Jymmm> No need to be fast
[17:23:46] <ve7it> no... its for a flashing fishing lure that flashes for about 1 week before the battery goes dead
[17:24:22] <Jymmm> Heh, does it work?
[17:25:42] <ve7it> not sure... it has been too windy all month to go fishing
[17:25:56] <Jymmm> ah, bummer
[17:26:28] <ve7it> raining today, but the water looks great
[17:31:26] <Jymmm> raining?! Eeeesh, and it's like 89F here
[17:31:33] <Jymmm> and dry as can be
[17:31:46] <Jymmm> too dry, lots of fires
[17:33:20] <ve7it> yea... very dry here as well.... no green grass, so the rain will be nice for a change.... really just showers, not like the SE where they get rain you need a SCUBA setup to walk through
[17:33:37] <Jymmm> heh
[17:33:59] <Jymmm> We are in a droght (again)
[17:34:32] <ve7it> gotta run.... the local boys have a friday afternoon bitch session that is about to start
[17:34:46] <Jymmm> ve7it: Field Day huh? lol
[17:35:02] <ve7it> last weekend!
[17:35:09] <Jymmm> err post field day
[17:35:30] <Jymmm> ve7it: I didn't do jack for FD =)
[17:36:02] <Jymmm> ve7it: Have Fun!!!
[17:36:06] <Jymmm> ve7it: 73
[17:36:13] <ve7it> me either.... didnt even turn on a radio to see how busy it was...73
[17:46:54] <maZer`-> im sorry my connection braking always :(
[17:47:35] <maZer`-> but i think i know whats my problem, my servo controllers moving only if the mesa card is sending more then 0,8V
[17:47:56] <maZer`-> is there any option i can setup in ini file that all <0,8v controller is not moving
[17:55:56] <pcw_home> Hmm sounds like the drives are in torque mode (or velocity mode is not working)
[17:55:58] <pcw_home> .8V ought to be 8% of full speed
[18:03:19] <maZer`-> hm its possible that drivers are in torque mode
[18:03:21] <maZer`-> im not sure :(
[18:03:59] <maZer`-> my machine got these controllers
[18:04:00] <maZer`-> http://www.heldt-rossi.de/produkte.php?Serie=SM805
[18:55:54] <anarchos> anyone know if leadshine controllers are the same as kelings?
[18:56:15] <anarchos> They look exatactly the same, just some different printing on them....and the leadshine's are a lot cheaper on eBay
[18:59:24] <Tom_itx> they are probably the same chinese source
[19:00:20] <anarchos> oops, wrong button ;)
[19:00:59] <anarchos> $50 + freeshipping for the Leadshine, or $70 + $40 shipping for the Kelings...
[19:01:03] <anarchos> not sure what to do :P
[19:01:49] <CaptHindsight> every keiling drive I've opened had a leadshine board inside
[19:03:20] <anarchos> cool I think I might take the plunge
[19:03:49] <anarchos> Any opinions on a breakout board for them?
[19:06:06] <anarchos> heh, even the model numbers kinda line up. Keiling KL-4042D vs Leadshine DM442C
[19:06:41] <CaptHindsight> LPT breakout board?
[19:07:57] <anarchos> yeah
[19:08:10] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/digital-stepper-motor-driver/3-axis-dsp-based-digital-stepper-drive-max-60-vdc-6-0a this 3 axis version connects directly to a LPT
[19:08:37] <anarchos> oh neat i didn't even see that
[19:08:41] <CaptHindsight> but I recently bought several low cost LPT breakout boards on ebay
[19:09:12] <CaptHindsight> some are better than others, working on a wiki review page
[19:10:13] <anarchos> i was hoping to use one of those TB5056 (probably messed that up) boards from ebay but I was scared away, heh
[19:10:50] <CaptHindsight> tb6560, are noisy
[19:11:25] <CaptHindsight> people that have lost their hearing over 10Khz don't mind them
[19:11:49] <anarchos> heh, i hear a lot do erratic things at high speeds
[19:11:52] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/breakout-boards/kl-db25-breakout-board
[19:12:14] <CaptHindsight> ^^ over priced and only 12V max on the input side of the optos
[19:12:35] <CaptHindsight> they come jumpered with the same 5V on both sides of the optos :/
[19:13:28] <CaptHindsight> http://www.ebay.com/itm/310702269807 http://www.ebay.com/itm/111149514180 testing these tomorrow
[19:14:24] <CaptHindsight> the Mesa boards are nice
[19:14:43] <anarchos> http://www.automationtechnologiesinc.com/products-page/breakout-boards/ethernet-smoothstepper-motion-control-board-with-terminals-for-mach3
[19:14:51] <anarchos> that still requires drivers, right?
[19:15:35] <CaptHindsight> and doesn't work with Linuxcnc
[19:15:59] <anarchos> o :/
[19:15:59] <CaptHindsight> mesa has a new ethernet board
[19:16:28] <anarchos> i still don't have a PC with a parallel port. it would be nice to not have to get a new one.
[19:16:36] <CaptHindsight> http://www.mesanet.com/fpgacardinfo.html 7i80
[19:16:52] <CaptHindsight> do you have PCI or PCIe?
[19:17:34] <CaptHindsight> I found some $10 pcie LPT cards and use them with PCIe extenders
[19:17:49] <anarchos> neither, i have a little nettop computer :P
[19:17:52] <anarchos> or a laptop
[19:18:11] <CaptHindsight> have you run the latency test yet on either?
[19:18:22] <anarchos> nope
[19:20:33] <Aero-Tec> upgraded to 10.04
[19:20:43] <Aero-Tec> can not get networking to work
[19:20:56] <CaptHindsight> anarchos: if the nettop doesn't have LPT then you'd have to use ethernet
[19:21:02] <Aero-Tec> keeps asking for password but one is not needed
[19:21:42] <Aero-Tec> any ideas?
[19:22:14] <CaptHindsight> ubuntu always asks for the password to change network settings
[19:22:15] <Aero-Tec> got 2 other linux units talking to my windows unit
[19:22:25] <Aero-Tec> not change
[19:22:28] <Aero-Tec> connect
[19:22:45] <Aero-Tec> it does not show up on my windows box
[19:22:50] <Aero-Tec> the other 2 do
[19:22:56] <Aero-Tec> not sure why
[19:23:03] <CaptHindsight> Aero-Tec: delete all the network connections
[19:23:13] <CaptHindsight> then create a new one
[19:23:16] <anarchos> CaptHindsight, yeah. not sure if i want to go ethernet or get a new PC for the mill
[19:23:17] <Aero-Tec> on the new upgrade?
[19:23:38] <CaptHindsight> Aero-Tec: yes, if it's acting odd
[19:23:42] <Aero-Tec> the new linux unit?
[19:23:46] <Aero-Tec> ok
[19:24:22] <CaptHindsight> Aero-Tec: I've had funny issues with the connection manager in ubuntu
[19:24:37] <Aero-Tec> deleted, now what?
[19:24:51] <CaptHindsight> create a new wired connection
[19:25:52] <Aero-Tec> connection name, will that be the name of the computer that show on the network?
[19:25:59] <CaptHindsight> Aero-Tec: and enter all the settings, then save
[19:26:33] <CaptHindsight> Aero-Tec: no, that's just the name for set of settings
[19:27:27] <Aero-Tec> how do I set up the computer name for network?
[19:27:29] <CaptHindsight> Aero-Tec: when you installed Ubuntu it asked you for the name of the computer
[19:27:58] <Aero-Tec> can I change it now?
[19:28:12] <CaptHindsight> I forget how in 10.04, let me check
[19:28:53] <anarchos> what's up with eBay sellers having a "submit best offer" option that's nearly exactly as the buy it now price?
[19:29:21] <anarchos> submitted an offer of $64 for something that was $64.99 and it was declined :P
[19:29:22] <CaptHindsight> http://www.wikihow.com/Change-Your-Computer-Name-in-Ubuntu
[19:29:51] <CaptHindsight> anarchos: never had that happen for a price that close
[19:30:37] <CaptHindsight> http://linuxgizmos.com/open-linux-hummingboard-sbc-goes-on-sale-starting-at-45/
[19:35:15] <anarchos> i was looking at that today
[19:35:30] <anarchos> does linuxcnc run on arm? :)
[19:35:41] <CaptHindsight> yes
[19:37:17] <LeelooMinai> SOme people run versions of it on Beaglebone Black and it's ARM, so yes
[19:37:22] <CaptHindsight> tested on the cubie2 and the bigotboardblack so far,
[19:37:37] <CaptHindsight> and the UDOO
[19:38:02] <LeelooMinai> I wonder if it could run on that banana pi
[19:38:24] <LeelooMinai> I think it's only $50 or so
[19:38:25] <CaptHindsight> LeelooMinai: should be fine, we're finishing up the howto
[19:38:49] <CaptHindsight> banana pi is $30
[19:39:01] <LeelooMinai> Where? In ali it's $50 or more
[19:39:06] <LeelooMinai> On ali*
[19:39:07] <CaptHindsight> on debian
[19:39:27] <LeelooMinai> What debian...?
[19:39:36] <CaptHindsight> http://www.bananapi.org/
[19:40:19] <LeelooMinai> It's the target price, but I don't think one can buy it for that (?)
[19:40:20] <CaptHindsight> Linuxcnc on debian for the allwinner A20 boards
[19:40:45] <anarchos> what about raspberry pi?
[19:41:45] <CaptHindsight> I forget, i think some had some variation of Linuxcnc on the Rpi, it's even run on an old mini2440
[19:42:00] <anarchos> hmm, because I have a RPi
[19:42:02] <CaptHindsight> and sam9 400mhz
[19:44:31] <CaptHindsight> https://code.google.com/p/miniemc2/
[19:44:52] <CaptHindsight> http://www.youtube.com/watch?v=w3Ls5ta7eg8
[19:45:05] <CaptHindsight> Linuxcnc (emc2) running on Pico-SAM9G45 ^^^
[19:47:02] <CaptHindsight> linuxcnc also runs on https://www.olimex.com/Products/OLinuXino/A20/
[19:47:30] <CaptHindsight> https://www.olimex.com/Products/SOM/A20/
[19:49:00] <CaptHindsight> LeelooMinai: that aliexpress sire has only sold 8 units, i wonder if they are just buying them at $30 and reselling

[19:49:50] <CaptHindsight> sorry for the flood
[19:49:54] <LeelooMinai> Well, this is 262 orders: http://www.aliexpress.com/item/Free-shipping-Banana-pi-fully-compatible-with-Raspberry-Pi-cubieboard-with-Gigabit-ethernet-port-SATA-Socket/1839648169.html
[19:51:35] <CaptHindsight> heh $52, I'd wait a few weeks
[19:52:53] <Aero-Tec> got it fixed
[19:53:04] <Aero-Tec> 2 computers had the same name
[19:53:27] <CaptHindsight> Aero-Tec: why did you do that? :)
[19:54:03] <LeelooMinai> He named one of them Bob, then decided to use that name in reverse for another one

[20:08:14] <Aero-Tec> thanks for the help
[20:08:25] <anarchos> awesome, thanks
[20:08:36] <Aero-Tec> I was installing on 3 comps at the same time
[20:08:51] <Aero-Tec> and did not know what I was doing
[20:08:53] <Aero-Tec> lol
[20:09:13] <Aero-Tec> one had a easy way to change the name
[20:09:22] <Aero-Tec> not sure why the others did not
[20:09:44] <anarchos> i don't even know much about my RPi
[20:09:52] <anarchos> i wonder if that's a legit lpt header on it
[20:13:46] <Aero-Tec> looks like the upgrade to 10.04 screwed up emc2
[20:14:07] <Aero-Tec> it was a old install
[20:14:21] <Aero-Tec> it will not run now
[20:14:25] <Aero-Tec> not sure why
[20:14:51] <kengu> sounds reasonable
[20:16:18] <Aero-Tec> not even in the applications list
[20:27:35] <kengu> emc2 is replaced by linuxcnc in more recent versions. but still there are reasons not to upgrade the system under. I did similar upgrades on a new install and figured it was not too good idea..
[20:37:12] <Jymmm> kengu: emc2 and linuxcnc are only a name change, nothing else.
[20:38:17] <LeelooMinai> They could name it emc^3 :)
[20:38:43] <Jymmm> LeelooMinai: Not according to the lawyers
[20:41:25] <gkamysz> aero, my upgrade was taking hours so i just gave up used the disk. other than video compatibility it was easy
[20:44:40] <kengu> Jymmm: true on that also. i should have stated renamed
[20:44:50] <Jymmm> =)
[21:31:05] <Tecan> happy jul 4 from your northern neighbors
[21:31:47] <Jymmm> Tecan: Happy Putine To you!
[21:31:58] <Jymmm> poutine
[22:28:03] <anarchos> welp, just bought 3 controllers :D
[22:28:51] <anarchos> need to decide on a breakout board and motors now
[22:30:19] <jdh> motors that work with the controllers!
[22:31:12] <anarchos> :P
[22:36:29] <RyanS> With this style of tool be good for quality finishing passes? http://www.ctctools.biz/servlet/the-611/indexable-iso-standard-lathe/Detail
